SEAL - WIPER (Komatsu KO3EA6413240)

A wiper seal that has lost its ability to exclude contaminants can allow debris to score a shaft surface, leading to progressive leakage. This aftermarket replacement references the Komatsu catalog and carries the cross-reference number KO3EA6413240. The seal's primary function is to scrape foreign material from a reciprocating rod as it retracts, protecting the internal sealing elements. A worn wiper seal often results in visible fluid weeping around the rod entry point, which accelerates seal degradation. Keeping the wiper seal in sound condition helps maintain the cleanliness of the rod surface during each cycle. Verify the serial number or application, then call (562) 693-7748. The part is an aftermarket component sourced from the Komatsu catalog.
